Taken today. This freshwater lake and marsh is in the Waikanae Beach area, a bit to the north of the lagoons.  According to the Wetland Trust website:

“Waimeha Reserve is surrounded by houses and is no longer regularly flooded by the Waikanae River. Nonetheless, it is a picturesque and relatively diverse lowland / coastal swamp with large areas of raupo, sedgeland, toetoe and a small lagoon. A local community group maintains the wetland.”

The standpoint of the first three photos above is the north side of 19-21 Eruini Street, while the boardwalk photo is a bit to the east, nearer to Queens Road which is the best entrance area.
